Online Chess Lesson Marketer Needed

I am looking for an experienced marketer to promote online group chess lessons for intermediate-level students. The lessons will be held via Google Meet for a group of 14 students. Each student will pay $5.99 per lesson. The lessons will be conducted twice a week, and the marketer will be paid based on the number of students who sign up and attend the lesson.

Responsibilities:

Attract students to sign up for the chess lessons.
Share a Google Calendar link where students can register and pay for the lessons.
Promote the lessons through suitable channels (social media, forums, groups, etc.).
Payment Terms:

I will pay based on the number of students who attend each lesson. The payment structure is as follows:
14 students — $25
13 students — $20.8
12 students — $17.1
11 students — $11
10 students — $10.7
9 students — $8
8 students — $5.7
7 students — $3.7
6 students — $2.1
5 students — $1
Fewer than 5 students — no payment will be made.
Requirements:

Experience in online advertising and promoting educational services.
Understanding of chess as a discipline is a plus.
Ability to consistently attract students on a regular basis.
Long-term Collaboration:

If the results are successful, there is potential for long-term collaboration.

Please include how you plan to attract students and which channels you will use.
